This is specifically about the GRoCS PLAnts ruleset, which doesn’t allow spinners or things that get hot. My next idea for an antweight would be a pneumatic rear-hinged flipper or a spring flipper (similar to the likes of Aaaaaaaaa! and Jhonny Mnematic), but as it may require a locking bar (see spring flippers), would it be allowed?

I would recommend making all your questions in 1 form, and continue to add to that. It’s rather inconsiderate to clog up the home page with multiple topics that could be put into 1
Provided a locking bar and I believe it should be allowed, I’ll ask ben if he would allow it at GROCS
